[PATCH v5 0/5] Add Texas Instruments BQ25703A Charger

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Add support for the Texas Instruments BQ25703A charger manager. The
device integrates a boost converter with the charger manager. This
series adds the device as an MFD with separate regulator and power
supply drivers. This allows us to manage a circular dependency with
a type-c port manager which depends on the regulator for usb-otg
but supplies power to the BQ25703A charger.

Changes since RFC
 - Corrected some minor issues with code and device-tree labels.
 - Replaced most of the manufacturer specific device-tree properties
   with monitored-battery properties.
Changes since V2
 - Added reference to power-supply.yaml and removed note for i2c
   address per recommendation from Sebastian.
 - Corrected documentation error for charger driver found by kernel
   test robot.
 - Corrected duplicate POWER_SUPPLY_USB_TYPE_PD entry and corrected
   ichg logic in power supply changed function.
 - Corrected missing linux/bitfield.h header in regulator driver found
   by kernel test robot.
Changes since V3
 - Changed name of regulator from usb_otg_vbus to just vbus to align
   with datasheet.
 - Additional cleanup of the device tree documentation.
Changes since V4
 - Replaced instances of dev_err followed by a return in the probe
   functions with a return of dev_err_probe instead.
 - Simplified cell definition of main driver for probe.
 - Updated copyright year to 2025 on copyright strings.
